P.K plumbing and heating have been installing new boilers and heating systems for over 35 years. We know the ins and outs of all types of boilers and heating systems. It doesn’t matter if it’s a complete new boiler, or you need an annual boiler service. We are here to help.

Boiler Installations

Boilers that are over 10 years old are uneconomical and waste a lot of valuable energy. The current building regulations stat that any replacement or new gas – fired boiler must be a condensing boiler. Modern condensing boilers improve efficiency to over 90% which could save you a minimum of 30% per year on your home heating bills, which represents a big saving over the lifetime of your boiler.

We specialise in the installation of condensing boilers, Worchester, Valliant and Ideal boilers are the main manufacturers at the moment and will give you up to 7 years warranty.

After we have installed a boiler, we can come back once a year to give your boiler an annual service making sure everything is working to the correct efficiency, and everything is working ok. It also keeps the warranty up to date.

Power Flushing

Power flushing your heating system stops the build up of sludge which will have occurred over the years. It also helps the overall flow of water around your heating systems which will stop cold spots occurring in each radiator, or even prevent some radiators working at all. Power flushing will also keep your boiler working at maximum efficiency. Every new boiler installation includes a free power flush.

Heater Repairs

No matter what type of boiler your house hold has we can quickly diagnose and repair your boiler using quality components and parts. All work is covered with a 1 year’s parts and labour guarantee and will be fitted by a qualified engineer.

Heater Servicing

Annual boiler servicing is a wise option, we can ensure that your current system is operating to a peak performance, preventing carbon Monoxide leaks and prolongs the lifespan of your boiler. Regular maintenance can also help prevent a system breakdown which can be expensive and never welcome.

What is a condensing boiler?

A condensing boiler is a high efficiency modern boiler that incorporates an extra heat exchanger so that the hot exhaust gases lose much of their energy to pre-heat the water in the boiler system.

When working at peak efficiency, the water vapour produced in the combustion process condenses back into liquid form releasing the latent heat of vaporisation.

A side effect is that this water, known as condensate, which is usually acidic, has to be piped away to a drain or soak away.

What size of boiler do I need?

Most existing boilers are measured by their output in British Thermal Units per hour (BTU/h), but all current boilers are sold in the metric equivalent of kilowatts (kW).

You should bear in mind that in the past central heating engineers often installed boilers that had a higher output than strictly necessary. Although this meant there was no possibility of the boiler failing to meet the demand for heat, even in the most arctic of conditions, it also meant that they were mainly operating at a part load, and so running below their maximum efficiency.

If you have installed additional loft or cavity wall insulation since the last boiler was fitted, it is highly likely that you will need a smaller boiler than before.

We recommend seeking professional advice from a GAS SAFE registered installer before choosing an appropriate replacement boiler.
